Theses virions are approximately 40 nm in diameter, which are known as one of the smallest enveloped animal viruses. It infects hepatocytes, also known as Dana particles. The genome of HBV is circular, partly double stranded, and approximately 3,200 nucleotides long. Dr. Baruch Blumberd first discovered HBV in 1963 when he discovered an antigen that had a presence of HBV in blood samples. Dr. Blumberd and his colleagues travelled around the world collecting blood samples. They specifically studied patients who had received multiple blood transfusions. After research, they found the antigen that caused hepatitis B, which was then recognized in 1967. Two years later, Dr. Blumberg and his colleague invented the hepatitis B vaccine. The hepatitis B vaccine was named the first anti-cancer vaccine from the US Food and Drug Administration due to its prevention of chronic hepatitis infections that resulted in the prevention of liver cancer due to HBV.
